fasciculus

(fə-sĭk′yə-ləs)
n. pl. fascicu·li (-lī′)
A bundle of anatomical fibers, as of muscle or nerve. Also called fascicle.

fasciculus

[fəsik′yələs] pl. fasciculi
Etymology: L, little bundle
a small bundle of muscle, tendon, or nerve fibers wrapped by a layer of connective tissue called the perimysium (muscle) or perineurium (nerve fiber). The arrangement of fasciculi in a muscle is correlated with the power of the muscle and its range of motion. The patterns of muscular fasciculi are penniform, bipenniform, multipenniform, and radiated. Also called fascicle. fascicular, adj.
